Analyst · Cowen and Company. Your line is now open
Thank you, Jennifer, and good morning, everyone. I'm honored to be here today as this represents Liquidia's first of what we expect will be many quarterly update calls after completing our initial public offering in July of this year and being listed on in the NASDAQ exchange. Thank you, everyone, for taking time this morning to join us. We're excited to update you on our pipeline progress, in particular around our lead product candidate LIQ861 for pulmonary arterial hypertension or PAH. We will also provide highlights during today's call of our financial results for the third quarter of 2018, and describe certain anticipated milestones for the remainder of 2018 and 2019. After our prepared remarks, we will be available to take your questions. With that, I will dive into our lead program, LIQ861, for which you may have seen in this morning's press lease that we had completed enrollment of the safety portion of our pivotal, open-label Phase III clinical trial, known as INSPIRE, or the investigation of safety and pharmacology of dry powder inhalation of treprostinil. As of October 24, we have enrolled 109 patients at our INSPIRE trial, completing the safety portion of the trial. Based on feedback from FDA, we believe that this trial will support the NDA filing for LIQ861, for which we are targeting our submission in late 2019. By way of background, LIQ861 is an inhaled dry powder formulation of treprostinil, utilizing our proprietary PRINT technology that is administered using a convenient disposable dry powder inhaler. We believe that LIQ861 has the potential to improve the therapeutic profile of existing formulations of treprostinil by enhancing deep-lung delivery and achieving higher dose levels than current inhaled therapies. The primary objective of the INSPIRE study is to evaluate the long-term safety and tolerability of LIQ861. The INSPIRE study is designed to evaluate patients who have either been under stable treatment with nebulizer-delivered treprostinil for at least three months and are transitioned to LIQ861 under the protocol, or who have been under stable treatment with no more than two prostacyclin oral PAH therapies for at least three months and have their treatment regimen supplemented with LIQ861 under the protocol. With the safety portion now fully enrolled, we are currently focusing our efforts on completing patient enrollment in our one-directional crossover substudy to compare bioavailability and pharmacokinetics, or PK, of treprostinil as the patients' transition from Tyvaso to LIQ861. Of the 109 total enrolled patient population as of October 24, 104 patients have received at least two weeks of LIQ861. We have completed enrollment of the safety portion ahead of original expectations, and as such, have updated guidance around anticipated timing for first data readout. We now expect to report two week safety data in the first quarter of 2019, followed by PK results from the substudy in the second quarter of 2019. In addition to the INSPIRE study, we are also conducting a clinical trial that explores the hemodynamic effects of LIQ861 in PAH patients. Although the FDA has not requested that we undertake this clinical trial and it is not required for the NDA submission, we believe the data may assist in further assessing the effects of LIQ861 on acute and chronic hemodynamic measurements and right heart function. Data from this clinical trial would also add to our understanding of safety, tolerability and PK of LIQ861. We expect to enroll our first patient in this clinical trial in the first quarter of 2019. As you have heard, great progress has been made this last quarter in advancing our lead program, LIQ861. We believe LIQ861 has the potential to overcome the limitations of current inhaled therapies and maximize the therapeutic benefits of treprostinil in treating PAH. PAH is a rare, chronic and progressive disease currently with no cure. We believe patients could benefit from a treatment option like LIQ861, possibly improving overall quality of life. As such, we remain focused on wrapping up the INSPIRE study, in particular the PK substudy, as well as supported CMC activities to prepare from our NDA submission of LIQ861. Shifting gears, I would like to now address our second and earlier-stage product candidate, LIQ865. LIQ865 is an injectable, sustained-release formulation of bupivacaine, a non-opioid anesthetic to treat local, postoperative pain for three to five days through a single administration. We have completed a Phase Ia clinical trial in Denmark and a Phase Ib clinical trial in the U.S. Of note, we recently had an abstract excepted at the American Society of Regional Anesthesia and Pain Medicine and anticipate presenting our Phase Ia safety, PK and pharmacodynamic results in 28 healthy volunteers. That meeting is being held November 15 through 17 in San Antonio, Texas, and we're excited to be a part of it. Our next steps for the LIQ865 program are Phase II-enabling toxicology studies. Two studies, bone and wound healing in small and large animals, are being initiated to evaluate the safety of LIQ865. Preparatory activities are underway, with the goal of having a Phase II ready asset in late 2019. We are extremely excited about the potential benefits both of our product candidates could bring to patients, and our entire team of Liquidia is committed to the process of completing the important development requirements. With that, I will now turn the call over to Kevin, our President and CFO, to cover the third quarter financial highlights.
